lIMPROVEMENT IN PAPER-CUTTING MACHINES.

Specification forming part of Letters Patent No. 149,690, dated April14,1874; application tiled February 21, 1873.

To all whom it may concern:

Be it known that I, 'SAMUEL W. SoULE, of the city, county, and State ofNew York, have invented, made,and applied to use a new and usefulMachinefor Cutting Paper; and that the following is a full, clear, and correctdescription of the same, reference being had to the accompanyingdrawings, making part of this specification, and to the letters ofreference marked thereon, in which- Figure I is a front view of mypaper-cutting machine, the front table being removed and the knifebeingin position to commence work. Fig. II is a front view of the same, theknife being shown in position after working. Fig. III is atransversesection of my paper-cutter.

In the drawings, like parts of the invention are pointed out 'by thesame letters of reference.

The nature of the present invention relates to improvements, as morefully hereinafter set forth, in the construction of a paper-cuttingmachine, and will be found to relate more particularly to the .meansemployed to operate the knife.

To enable those skilled in the arts to make and use my invention, I willdescribe the same.

A shows a frame for supporting the operative parts of the machine,and Bis a table, upon which the paper to be cut is placed. Held in the frameA is one endof the shaft G, having secured upon it a cog-wheel, D, andattached to it a lever or handle, E 5 or, in lieu of the lever, suitablegearing for other than hand-power. Upon the opposite side of the frame Ais a roller, F, free to revolve upon its axis. Upon this spindle, also,is held one end of guide-bar Gr, the opposite end of the same being heldupon'a stud inserted in the upright portion of the frame A. H shows theknifebar supporting the knife I. This knife-bar has gearing J attachedto one end of its inclined bottom edge, in direct line with its motion,while the opposite end is inclined in like direction, sokthat whenplacedl in position in the machine the gearing J shall engage with thecog-wheel D, and the opposite inclined end shall rest upon the roller F.K shows the front table of the machine, made movable for the purpose ofclearing the table from the knife and knife-bar, and supported by thebrackets L and L2, one of which is provided with a steady -jpin enteringint-o the frame A, and the bracket L2 being provided with openings, sothat they may be passed over a rod, M, projecting from the frame A.Passed over this rod M, and confined between the rear bracket L2 and acollar, N, held upon the rod M by a set-screw, a, is a spiral spring,-O.The clamping device by which the paper to be cut is secured consists ofa plate, P, and plate It,

connected by the side rods Q. The plate It is provided, about centrally,with an opening having a female screw-thread cut within the same, withwhich the male screw S engages.

A hand-wheel, 24, is secured upon the end of this male screw S, andbetween the cross-bars P and R, and the upper end of the male screw S isfree to-revolve in abracket, T, secured upon the under side of the frameA. To the front of the cross-bar P is held a plate, U,`a screw, V,passing through thissecondary plate, and having a spiral spring, W,passing over it, and having its bearing upon the face of the secondaryplate U and the head of the screw V. Pins b inserted in the top plate P,and entering openings in the secondary plate, steady and guide the sameas it moves, as described hereinafter. machine. This consists of a plainplate of metal, made true upon its face and bottom edge,

secured upon the rody Y, which rod is free to move in openings in theupright portion of the frame A and the standard Z. A set-screw, c,inserted in the upright, is used to hold the paper-gage in any desiredposition.

Such being the construction, the operation is as follows: The knife-barand knife are placed in position in the machine, the gearing upon oneend of the knife-bar engaging with the cog-wheel, and the oppositeinclined end resting upon the roller. chine is placed in the properposition by moving the rod Y, to which Ait is attached, either backwardor forward, as may be required, and fastening the same in position bytightening the set-screw c. They paper is now'placed upon the table B ofthe machine, and the hand of the operator being placed upon theclampwheel 24, and the same being turned, the rod s, entering into andengaging with the screwthreaded opening in the plate It, causes the .frshows the papergage of the The gage of the ma- A clamp to be drawn down.As already described, the rods Q, which support the crossbar P, areattached to the cross-bary R, and, as the same is drawn down, the topplate is drawn down upon the paper, confining the same between the tableand itself. The paper is now in proper position to be cut. By graspinglever or handle E upon the shaft G and turning the same, the cog-wheelengages with the gearing J upon the knife-bar H, and elevates the same,giving to the knife I a lateral movement through the paper, the oppositeend of the knife-bar rising upon the-roller F, and being guided by theguide-bar G. As the knife passes throughl the paper the front table K`yields to correspond with the increased thickness of the knife and bar,and clears the paper cut off from the bar. As the same is thrown forwardthe spiral spring O, held upon the rod M, between the bracket L2 and thecollar N, is compressed, and after the knife passes through the paper,the plate U, attached to the plate P, as described, yields to the knife,and is thrown forward, compressing the spiral spring W between itselfand the screw V. The paper having been cut by this lateral movement ofthe knife, the lever or handle E is turned in the contrary direction,and, the cog-wheel D engaging with the gearing J upon the knife-bar H,the knife and knifebar are drawn down to their proper position. As theknife descends, the spiral spring W is expanded, and returns thesecondary plate to its former position, and the spiral spring O isexpanded, and restores the table K to its former position.

The lever E can be pla-ced in any desired position before cutting by,raising the end of the knife-bar out of gear with the pinion, and,having turned the lever in the desired position, restoring theknife-bar. When the knifebar recedes, it is arrested at its farthestextreme-by the rod M, which is necessary in cutting paper on the table Bbut when paper is cut by a pattern, then the knife is to be arrested bythe levers striking a stop.

The knife-bar can be placed in any desired position by resting the leveragainst a stop, and raising the bar out of gear and pushing it up ordown, as desired.

Having now set forth my invention, what I claim as new isl. The yieldingtable K, substantially as and for the purpose specified.

2. The combination of the yielding table K, knife-bar H, knife I, rollerF, gearing J, shaft C, and cog-wheel D, as and for the purposesspecified.

3. The combination of the cross-bars I? and R, side rods Q, hand-wheel24, and yielding plate U, as and for the purposes set forth.

4. The combination ofthe gage a', rod Y, and set-screw c, the rodsliding longitudinally, and capable of being partially rotated, so thatthe gage may be moved along the table and turned off of and away fromthe table, for the purposes set forth.
